[Milsurplus] LCR Meter With Useful "L" Ranges?

[Mike Feher]

I used to love my antique Boonton 190 for measuring sub micro-Henry
inductors. Heck, it was an antique back in the late 60's when I first got
one. Built many HF and VHF filters by using it. Still a great machine, but
of course, smaller and better are easily available now. 73 - Mike

I know of one machine that can measure under 1 uh.  You will find them on 
Ebay and at the flea-tussles.  It's called a Tektronix type 130 LC meter. 
They have six ranges: 0 - 3 uh, 0-30 uh and 0-300 uh.  Also capacitance in 
three bands to 300 pf.  It uses tubes and each band may be calibrated easily

with a standard inductor or capacitor.  I've had one here for years and get 
very good results with it.  The last inductor I checked with it read .6 uh 
and was found to be correct.  Flea market price is around $25 more on Ebay. 
Matching calibrator box cost a bit more and really isn't necessary.  A box 
of standard value caps and coils is.  No reisitance measurements available 
in the 130.  Beware of inexpensive Chinese meters they have zero acurracy in

the UH or PF range but are OK for reading .1 uf and above.
